3 Claims.

This invention relates to window constructions for motor vehicles, as buses, and has for its ob- `lect a. Window embodying complemental sashes for closing a single window opening in which one sash, and preferably both, are slidable endwise relative to each other to partially open the Windowopening,which Window constructionisparticularly simple and economical in construction and readily installed by the bus manufacturer, it being understood that the window equipment is supplied by one manufacturer, as a unit, and installed'in position in the car body by the bus manufacturer.

It further has for its object a window unit construction in which the Window frame is slidably interlocked in weather tight relation with both sashes by means of ribs on the frame and grooves in three sides of keach sash for receiving the ribs on the top and bottom and upright window frame members.

It further has for its object a particularly simple and eicient means for shifting one sash or each sash to partly open the window opening and for holding it in its shifted position.

It also has for its object a simple and economical construction by which the sash frames which slidably interlock with ribs on the window frame can be readily demounted.

It further has for its object a particularly 30 simple and eicient construction and assembly of a window frame and window of this type.

It also has for its object an arrangement of the guide ribs on the lower window frame, whereby water is prevented from accumulating and can run out from the channel between the two parallel guide ribs on the lower window frame member.

'Ihe invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.

In describing .this invention,v reference is had to the accompanying drawings in which like characters designate corresponding parts in all the views. y

Figure 1 is an elevation, partly in section, of this window construction unit.

Figure 2 is a sectional view on line 22, Figure 1, the sash being removed.

Figure 3 is a sectional view on the plane of line 2 2, Figure 1, the contiguous portion of the car body and structure being alsoshown.

Figure 4 is an enlarged, sectional view on line 4 4, Figure 3, the contiguous portion of the cary body being also shown.

Figure 5 is a sectional view taken on the plane frame member of the of line 5-5, Figure 4, showing the bottom frame member, partly broken away, and also showing one of the upright side members of the window frame in section.

The window frame comprises top member I, bottom member designated generally 2, and side or upright members 34, the top member being formed with a pair of parallel ribs 5 and 6. the bottom member being formed with similar ribs 'I and 8, and each of the side members being formed with a single rib 9, I0, the ribs 5, 1 and 9 being alined and the ribs 6, 8 and I0 being alined. The ribs 5, 1 and 9 constitute one set and form a guide for an outer sash II and the ribs 6, 8, I0 constitute another set and form a guide for an inner sash I2, these sashes together iilling the opening of the window frame, when closed, and each is formed with grooves extending inwardly into the outer edges of the top rail, one stile and the bottom rail, for receiving the ribs'. These grooves are lined with a suitable yielding material I3 which makes the sashes weather tight and holds them from rattling. 'I'he ribs 5, 1, and 9 extend into the grooves of the outer sash I I and the ribs 6, 8 and I0 extend into the grooves of the 25 inner sash I2. As seen in Figure 3, the sash frames overlap each other and the stiles I4 and I5 areV in overlapping relation, when both sashes are closed, and also the stiles I4 and I5 have coacting means to close the crevice between the lapping 30 portions, when the sashes are closed.

As here shown, the stile I4 of the outer sash II is formed with a flexible resilient Weather strip I 6` which wipes on the inner face of the stile I5 when the sashes are in closed position. Each sash is slidable horizontally, the outer sash being slidable along the Ways or ribs 6, 'I out of and into engagement with the rib 9 and the inner sash I2 being slidable along 4the ribs 6 and 8 out of and into engagement with the rib I0.

The window frame is formed of sheet metal, the upper frame member I being angular in cross sectionwith the ribs 5 and 6 folded up therefrom. The frame member I is here shown as provided with an upwardly extending ange I1 which laps the outer side of the frame structure of the car or bus body. Likewise, the upright window frame members 3, I are formed of sheet metal with the ribs 9 and I0 folded therefrom and are also formed with outwardly extending ilanges I9 which are lapped on the outer faces of the frame structure of the car or bus body and secured thereto in any suitable manner, as by fastening members 20.

As here shown, the contiguous portion or post structure 2| of the car or bus body is shown as sheathed in a sheet metal casing 22 and also a strip 23 is interposed between each upright member 3 or l and the trame or post structure 2i.

The upright members are additionally secured to the frame or post structure by fastening members 24 which extend through the upright frame members 3, and the the frame or post structure 2i.

The bottom member 2 of the window frame is also formed up of sheet metal and includes a base or sill portion 25. This includes an, intermediate portion inclined out of a horizontal plane and upwardly extendingenge 26 at the inner side oi' the window structure and downwardly extending ange 21 at the outer side of the window structure, thus lapping around the window opening in which the window frame is mounted. This member 28 is also sheathed in a sheet metal casing 23, one wall 33 of which is formed with a'raised ange or bead Sion which the inner edge of the base or sill member 25 rests.

The lower frame member also comprises an angular strip 32 usually formed of sheet metal and having provided thereon the ribs 1. and 8, which rise from the horizontal portion of the strip 32. The angular strip 32 also has outer and inner downwardly extending anges 33, 33e, which rest on the sill member 25, the inner flange abutting against the ange 26 on the 'base 25 and being formed with notches 33h which provide passages for the brackets 35 when the strip 32 is being removed and replaced during removal and replacement of the sash, as hereinafter described. This angular strip 32 is secured to the base or`sil1 member 25 in any suitable manner, as by screws 34, extending 'through the ange 33 into upright arms of angular brackets 35 secured, as by rivets 36, to the intermediate part of the sill member 25. The rib 8 iS folded up from the strip 32. The rib l is interruptedto provide passages 31 and for convenience informing the rib l with the passages 31, said rib is usually formed of separate alined sections, spaced apart and secured to the strip, in any suitable manner, as by a riveting operation.

The purpose of interrupting the rib 1 constituting the 'guide for the outer sash is for permitting water to drain from between the guides l and 8, when both sashes are closed, it being understood that in wet weather both sashes are ordinarily closed.

In operation, the sash l2 can be opened by sliding it along the ribs 8 and 8 to the left (Figure 1) and likewise, the sash il can be opened by sliding it to the right along the ways 5, l.

To initially assemble the sashes in the frame or afterwards remove and replace them, the strip 32, being detached, is applied to the sashes with the ribs 'i and 8 in the grooves in the bottom rails of the sashes li, i2. The sashes are slid to overlap suiiiciently so that their stiles will clear the ribs 9, l0 or so that the over-:all width of the two sashes so overlapped is less than the distance between the ribs 9, iii. The sashes are then tilted to t the grooves in the upper edges of the top 'rails of the sashes over the ribs 5, 6. The sashes with the strip 32 applied are moved from tilted into upright position within the frame, the notches 33b passing astride the brackets 35. The screws 34 are then applied. The sashes il, l2 can now be slid into normal position, causing the grooves in the outer stiles thereinterposed strip 23 into the frame member 28 of to ilt over the guide ribs 3, lil. The reverse or this operation takes place in removing the sash. The window frame is tted to the window opening in the vehicle body until the flanges l1, i9 and 21 abut against the outer face of the vehicle body around the window opening, and the bottom rail 2E rests on the ange 3| and then secured by screws passing through the anges l1, is, 21 into the car body.

'Ihe sashes are normally held in their closed 'or any one' of a number of open positions in any suitable \manner, as by bolts 38, 38, suitably mounted in guides 40 formed on base plates di which are secured to the lower corners of, the sash, the bolt 38 of one sash, as the inner sash I2,

coacting with sockets 43 formed in. the upper edge of the flange 26 and the bolt 38a coasting with sockets 43 in the edge of the guide rib il of the sill member 25. These bolts are springpressed and have handles 44 arranged in pinchhandle relation to stationary abutments 45 provided on the outer stile of each sash.

Owing to this window construction, and particularly to the guide ribs, the sashes are readily operable and always held against rattling and are always weather tight when closed. Furthermore, the entire unit construction consisting of the frame and sash is particularly economical in construction .and readily applied by the car or bus manufacturer.
